This was the art of the Ark Aberration DLC launch, it was also used as a huge wall printed. the original painting is 25k pixels wide.
it was made blending a lot of techniques. I got some assets from the modelers and animators from the studio. posted them in Maya, then rendered some things on 3ds max using Octane. a lot of things are solved with photos and required a ton of painting to make it look seamless in such a busy composition.
